DeneDown

Sets your PC to sleep, hibernate, shutdown, or restart based on your time setting. Time may be set between 1 minute to 24 hours (in 1 minute increments). Countdown timer displays time remaining until the action occurs. This is a combined x64/x86 version.
(Note: Tool is idle when time reads 0 hr:0 mins)

Consider Windows 10 has changed the console "shutdown.exe" command to be active only for 30 minutes max. With DeneDown, you can extend your sleep/shutdown/hibernation period much longer, as it was in previous Windows versions. This is particularly useful when you are leaving your system to let it image the drives, but do not want to leave your PC on after completing the imaging.
